SW40-187A and 188A open valves SW-V-187A and 188A to provide Standby Service Water (SW) System cooling to FPC-HX-lA.

4.0 ALIFICATION STATUS 4.1 Sugar of uglification Status The motor operators were purchased qualified; however, unqualified motors were inadvertantly used.

The vendor is scheduled to provide qualified replacement motor>-

The following justification for interim operation is provided in the event that the motor operators are not replaced prior to fuel load.

4. 2 Parameters Re uirin Justification Temperature,

pressure, humidity and radiation dose.

7183f/1

5.0 JUSTIFICATION FOR INTERIM OPERATION Alternate cooling water is provided to FPC-HX-lA through valves SM-V-187A and SM-V-188A.

Although fuel pool cooling is not required until the first refueling outage, the valves must remain closed in the interim so'hat operation of the Standby Service Mater System would not be degraded.

The aotor operators will be qualified prior to the first refueling outage.

Currently the motor operator s Review of the construction of oper ators with similar motors that would cause the operator are fully qualified except for the motors.

the operator and limitorgue test data on identifies no failure mode of the motor to open the valve.

6.0 CONCLUS ION Interim operation is justified on the following basis:

SM-NO-187A and 188A are not required to operate post-accident since fuel pool cooling is not needed prior to the first refueling outage.

2.

There is no failure mode of the motor that would cause SMNO-187A and 188A to open their associated valves to an undesirable position.
